, ments in Typewriters and I do hereby declare the followingto be a full, clear, and ex; act descri tion of the invention, such as will enable-otl iers skilled in the art to which it ap ertains to make andjuse'the same.

he present invention relates to typewriting machines, in which a rotary platen occupies a printing position just in rear of a. type-guide and a ribbon-vibrator, which render it difiicult to insert sheets down wardly in front of the platen, and to collate them on the platen. According to the present invention, the platen and a collating table are displaceable from normal or typing position forwardly over said print ng instrumentalities to a position where'inter- -ference from the type-guide and ribbon is avoided, and where other functions, such, for instance, as-sheet-collatin'g, inserting and arranging, ma hence be more conveniently effected; the p aten being presented conveniently or accessibly to the operator for in-u troducing-the sheets bottom-end first around the platen'at the collating operation, without liability of fouling upon the type-guide and ribbon-vibrator; y

In its-preferred form, the invention includes a tableor board onwhich work-sheets may be collated or arranged, and which is mounted to be displaced with the platen from normal or typing position to a position in which the sheet-co lating or arranging is effected. v i Y In a front-strike machine, such, for" in stance, asthe Underwood, thereis usually provided an apron .or paper-guide .W hich passes around th e lower art of the platen" 17.tothe front thereof, w ere it forms, the platen, a mouththroughfwhich the-typewritten sheetsare ejected, top-end'foremost. 1

Certain parts of the printing mechanism, as,

, for instance, the rib n ribbon-guide and jpe guide, are positioned in front of the platen, above the forward end of the apron vention is the provision of means whereby,

mechanism to a station or position where the sheets may conveniently be inserted bottomend first into the mouthde'fined by the platen and the apron at the front of the platen,

and thence be guided by the apron onto the face of the platen to such position thereon as may be desired for commencement of the writing.

More particularly, where a collating table .is employed, the invention provides means for translating the platen and the apron over and clear of. position where the sheets may be assembled on the table with their bottom-ends in, for in line with, the mouth formed by the apron and the platen; and thereafter be guided, bottom-end first, from the table to the platen by means. of the apron. v i

A feature of the invention, in the preferred form thereof, means- (such, for instance, as the usual re leasable feed-rolls), whereb a sheet, which has been guided bottom-en firstto' a given' station, and. thus held against any disarrangement. I

-A feature ofthe invention is the proavision fora bodily floating movement of the I platen, and associated parts, forwardly from the normal to the sheet-arranging position (as distinguished, for instance, from a mere is the provision of angular-swingof these arts), whereby the platen in collatingpositlon may present the proper sidethereof to the operator, and

whereby ease of action may beobtained by distributi-ng and balancing the weight of the parts, and by suitably arranging the several pointsof support, and constructing the supportgconnections By relatively compact In anisn brought to the most desirable position, and "automaticall into correct angular for'sheet -col ating or arranging. 1

the parts ay be setting,

however, being shown.

In effecting the floating movement of the present invention, in the preferred embodiment thereof hereinafter described, the platen is set in a bearing-piece, frame or mount, in which it has its normal line-feed rotation, and this frame may also carry a collating table The frame forms a member of a linkage, being connected to the typewriter-carriage by a plurality of lmks or sets of links, which are pivoted to the carriage. The diiferent sets of links or arms move on different axes on the typewriter carriage, and are pivotally connected to the frame at separated points. As one part of the frame follows the angular swing of one set of arms, the other set of arms supports the frame at another part thereof and causes the frame to be rocked withrespect to the first set of arms, so that a combined bodily and floating action is obtained, which may be made to result automatically, or without further adjustment, 11'1 appropriate angular settings for the parts with respect to the line of vision when said parts come to rest in sheet-arranging position at the end of their forward throw.

-Another feature of the invention is theprovision of means whereby the several sheets of work may be assembled and. conducted to the printing position ofv the platen without disarrangement and without/being provided with any alining devices. I

It is a feature of the invention to present the platen in the sheet-arranging position in such a manner that the collated or arranged sheets may there be clamped to the platen, as by means of feed-rolls, and, as so arranged and clamped, may be carried with the platen back to thenormal or typing position of the latter. In this connection, the invention may provide not-only for a collating board movable with the platen in fixed relation thereto, between normal and collating positions, but also'for movement in fixed relation'with the platen, between these positions, of a paper-shelf or other feed-roller support. V x

A further feature of the invention resides in so constructing the device that it may be attached :to typewriters of various forms now in commercial use, with the minimum alteration of the typewriter constructions;v In the accompanying drawings,

.Figure 1 is a perspective view ofthei'nvention, showing the same attached to a typewriter, only a portion of'the latter,

Figure 12 isa detail of the sheet shelf of modified forms of sheet, guiding devices.

In the drawings I have illustrated a portion of a typewriter which includes a frame 1, the feed-roller rod Qand the shift rod 3.

The frame of the collating device com prises side bars 4:, which are secured together at their ends by transverse rods 5. The collating board 6 is securedv to this frame at one end by'screws 7 and at the other end by brackets 8, which extend transversely of the board and beneath the same,

the ends of the brackets being-depressed, as shown at 9, so as to afford a free passage for the slides of the sheet clamping means,

' as will appear. Fast to the typewriter-can,

riage, on either end thereof, are brackets 13,- and pivoted on an axis, indicated at 12, to the brackets 13, are links or arms 10, which are pivotally connected at their other ends at 11 to the side bars 4 of the frame which carries the collating board and platen, so that this frame, and associated parts may swing on the axis 11 with respect to the carriage, so as to obtain the desired movement.

Moreover, a certain part of the weight of the frame may thus be received at the axis 11 and carried by the brackets 13. at the rear of the typewriter-carriage. The brackets 13 may be 'bracedvby a transverse rod 15 which extends-beneath the collating board. The free end of each of the links 10 pro- 'jects beyond'the pivot point'12 and is adapted to engage a pin 16 extending from the collating board ih's'ubstantially ahorizontallposition. At the edges of the collating board, but slightly spaced therefrom, are

0 which the positions,v

12s adjacent sidebar 4, so as to maintain the.

.35 of the lower bar.

tra'ted' clearly in Figure 1.

.of the several sheets to be collated are determined, as will be readil understood.

It will be seen that t e several sheets of paper, with the carbons interposed between them, may be placed'upon the sur-- face of the collating board 6, with the edges abutting the scale 17 and thus properl arranged -to subsequently be fed to the p aten 17 a in printing position.

In order that these sheets may be held in the proper relation to each other on the collating board, I have provided a sheet-clamping device which includes a pair of slides 18. These slides are mounted and operate upon the side edges 19 of the collating board, as clearly shown in Figure 1. A bar 20 extends between and is secured to these slides 18, the intermediate portion of the bar being provided with a depression 21 for a purpose which will later be described. A plate 22 is secured to one of the slides 18 by suitable 'fasteners 23, and this plate is provided with an upwardly-extending leaf spring 24. A hinge member25 is mounted on the plate 22, and one of the leaves of the hin e is provided with a projection 26, against which the spring 24 bearsto normally hold the hinge in such position that the upper clamping bar- 27, which is secured to the hinge at 28', is held parallelto the lower clamping bar 20. On the end of the upper bar 27, opposite to the hinge end, a spring-pressed tongue 29 is mounted, the

tongue being arranged to co-operate' with a socket 130 to form a latch to hold the clamping bar. :;27 in position. A sheet enga ing bar 31 is located between the clamping a'rs 20 and 27 and is yieldingl mounted on the upper bar 27 by means 0% guide screws 32 and coil springs 33. This sheet engaging bar 31 is formed to fit in the depression 21 in the lower bar 20 and is provided with a bill 34 which overhangs the beveled edge The sheets of work pass over the lower bar 20 and are clamped against the same by the resilient pressure through the sheet engaging bar 31, so that all possibility of relative movement of the sheets which are being collated is. obviated. In order to prevent the. upper :portions of the sheets from falling away from the col lating board 6 when the latter is swung to its vertical position, a pair of resilient fingers 36 issecured to the upper bar 27 and extends over the collating board, as illus- A bar 36' extends from one slide 18 to the other and is located beneath the fingers 36. 36' assists in maintaining the'sheets of work in position since the sheets are insertedbeneath it. g

Located beneath the collating board 6 and mounted in the side bars 4 of the frame, arejrollersfl37 and 37', around which endless bel'ts' j- 38 pass. These belts are secured to bars 4 of the frame.

This bar clamps 39 on the slides 18 andhave counterweights 40 interposed therein. These counterweights 40 operate on guides 41, which are mounted on the inner sides of the side Thus when the sheet clamp is moved in either direction, the weights will be likewise moved.

The side bars 4 of the frame are provided at the ends, opposite to the ends between which the roller 37 is mounted, with sockets 41' in which spindles 42 projecting from the endsof the platen are supported. The platen is thus supported by the side bars 4. These spindles 42 are mounted within yokes 43, which extend into chambers 44 in the ends of the platen and are secured in place by plates 45. These yokes are provided with slots 46 through which slide pins 47 project, the pins being extended through the spindles 42 to limit the sliding movement of the spindles longitudinally within the yokes 43. The spindles are normally pressed outwardly by coil springs 48 and are provided on their ends with abutment nuts 49. The- 'pins 47 in the slots 46 limit the movement of the spindles. The ends of the spindles 42 are provided wit-h clutch members 50,

which co-operate with complement-a1 clutch members 51 These clutch members 51 are mounted on the trunnions 52 of the platen rotating mechanism, which mechanism includes-the usual hand knobs 53 and also, the ratchet mechanism 54. These complemental clutch members 51 are attached to the platen rotating mechanism of a present commercial typewriter (the Underwood) with very slight modification of the mechanism. aswill be obvious from an observation of Figure 5 of the drawings. The springs 48 maintain the clutc-hmembers 50 and 51 in engagement each other when the platen is in its printing position, but the springs 48 are held under compressionand the clutch members 50 are retracted, during the swinging of the platen, either tool from its print-ing ,position, by controlling levers 55, which are the board is moved from its horizontal position, in which position the-sheets are placed upon the board, to its vertical position, the platen is swung into its printlng position and the co-operating clutch members 50 and 51 are operated to engage so that the platen rotating mechanism. may be effective to engage the platen. The ends of the side bars 4 at this time'engage in notches '57 which are formed in the'rod 2.. The engagement of the bars 4 in these notches prevents the frame from having any lateral movement when the frame is disposedyertically.

The frame which carries the platen-collating board is not, however entirely supported and controlled in its movementby the links 10, which Work on the axis. 12 on the carriage and the axis 11 on the frame. The frame, forward of the axis '11, is carried by another link or set of links which connect with the forward part of the type writer-carriage. These links, shown as 59, are pivotally connected at an axis 60 to lugs 58 on the front cross-piece of the typewritercarriage, and, at their other ends, are pivotally connected at an axis 61 to swing on a rod 62, carried by the side pieces 4 of the frame in the proximity of the platen. When the collating board is bodily translated or floated on the system of links. from its horizontal tof i ts vertical, position, the links 59 assume a position such as illustrated in Figures 3. and4 of the drawings and support the lower end of the board.

Threaded bolts 59', which are secured at 60' to the sidebars 4 of the-frame, support at their lower ends a rod 61, which rod may be adjusted vertically by means of nuts 62'.

on the .bolts. This rod 61 is secured to and supports a Sheet-SheIfand guide 63, which I is curved to conform to the curvature of the platen and which is extended and has attached thereto at 64 links 65. These links 65 are pivoted at the ends'opposite to the attaching means 64 at 66 to the side bars 4 of the collating frame. Openings are formed in the links 65,- and extending through these openings are cams 68, which are provided with operating handles 69 and which move in slots 67 in the links 65 during the movement of the sheet-shelf to and from the platen. When the cams 68 are turned so that the long diameters thereof extend at right angles to the short diameters of the slots 67, the sheet-support Will be locked in position away from the platen. Springs 71, which are attached at 72'to the side bars 4, and at 64 to the links 65, by drawing upon the links 65 tend'fto' swing the same upward around the pivot 66 to lift and maintain the sheet-support in normal position, so that the guide rollers 73, which are mounted on the outside surface of the support and extend through openings 74 in the same,will be held in'contact with thetionof the device is shown. In this form the bolts 59", which correspond to the bolts 59 in the reviously described form, are attached t e rod 61 and are rigidly secured to the side bars 4.. The rod 61' extends along the outer surfiace of the guide 63 and through keepers 63" which permit the guide 63 to move relatively to the rod 61 during the throw of the sheet-shelf to apply and release the feed-rolls.

In the third form disclosed in Figure 15, the bolts 59" are pivoted to the side bars of the frame and are attached to the rod 61'. The rod in this case carries the rollers 73. Therefore, when this form is used the rollers 73 of the first described form will be dispensed with.

As above noted, the paper-shelf or guide is carried by the collating-board frame when the lattermoves between Figure 1 and Figure 4 positions, (or between the dotted-line and full-line positions at Figure 1), and the feed-rollers 73 are carried with the papershelf from one position to the other, and the position of the platen with respect to the collating board and feed-rollers and papershelf, is maintained in all positions of the collating-board frame. This enables the platen and the feed-rollers to be used as a means for clipping or securing the lower portions of the sheets when the same have been collated, that is, for maintaining the sheets in position against the platen during the return movement of the parts to normal position. During the collating of the sheets the rolls are cast off. It is merely necessary to throw off the feed-rolls and to move the bar 27 forward, so that the bottom ends of the sheets may pass down between the feed-rolls and the platen. The feed-rolls are then thrown back. onto the platen, and, in this relation, all parts are moved backwardto normal or typing position. Therebeingno relative movement between the platen and the collating board, there is no pull or crumpling of the sheets.

Of course, it will be understood that after the sheets are clamped in place on the collating board, and. the board has been returned to normal or typing position, the sheets may be fed to the printing position' by feeding the sheets between the sheet-support 63 and the platen from the front to the rear of the latter. As the printing is subsequently done, the sheets will be fed in the reverse direction, as will be obvious.

While the operation of the device is though to be obvious from the preceding description, a brief rsum is here given. The collating'board 6 is in its horizontal position when the work is applied thereto. The sheets which are to be collated; are placed upon the board 6, being located under the bar 36' and over the lower clamping member 20, the upper member 27 having been swung into the position shown in Figure l0,*that is to say,,away from the member 20. The sheets are properly assembled in this position by meansof the scales 17, and

the upper clamping member 27 swung into position to hold the sheets in place. With the feed-rolls released, the slide 20 may be moved forward to introduce the ends of the sheets between the feed-rolls and the platen, and the feed-rolls then thrown back to the platen to hold the ends of the sheets in place. The collating board is then swung into its vertical position, concomitantly with the swinging of the platen 17' at Figure 1 back from its dotted-line collating position to its full-line printing position, at which ."time the sheets of work will be supported I frame. I

from two axes on thetypewrlter-carriage by the bar 36 and the fingers 36. The c utch members 50 and 51 will move into alinement with each other and when the controlling levers are operated to release them, they will automatically be engaged by the springs 48. The platen will at this time be in printing position, and the frame will be held against lateral movement by the engagement of the side bars 4 in the notches 57. \Vith the frame inits vertical position, the sheets of work are fed between the platen and guide 63 until the top line to be printed is in proper position. The work-sheets are then released from the clamping device 27. Thereafter the sheets will be moved in the reverse or line-feed direction in the usual manner. a.

' It will be noted, upon referenceto Figures 4 and 1, that, in the movement of the parts from normal to sheet-arranging positions,

the lower end of the frame is carried upward and forward on. the links 59, which serve as 'a' partial support or guide for the frame, and that, in so far as the frame is supported or guided by the links 59, it is supported from the front part of the typewriter-carriage. During this movement,

the frame, at a point intermediate thereof, is.

held or guided b the links 10 in such manner as to cause'the rameto be folded down and to be supported by the links 10 from the brackets 13 at the rear of the typewriter- The frameis thus bodily floated and two axes on the frameitself in its movement between the normal and collating positions. The frame may thus preferably be balanced to acertain degree, and its weight so distributed as to make the action easy for the operator. Moreover, in a single movement, not only are the parts brought forward, where collation may be conveniently effected, but they are automatically thrown to such an angle and position as to permit of easy. sheet-assembling.

The printing instrumentalities of the typewriter usually include ty e-bars (not shown) and a type-guide 7 5', igure 1, as well as a ribbon-vibrator 76, both of these being so close to the platen 17 as to interfere with the insertion .of work-sheets down around the front of the platen. This difiicul'ty-is overcome by floating the platen from full-line printing position at Figure 1 forwardlyover the printing instrumentalities 75, 76, as well as over theinking-ribbon (notshown) to the dotted-line sheet-collating position, the printing line on the platen belng always in the line of vision or foremost, as indicated by the arrow-at 77.

It will be obvious'that,'within the scope of the invention, the structure hereinbefore shown and described may be considerably.

modified, particularly as to the means whereby the floating action of the parts is attained, and as to the positions assumed by' the parts for sheet-arrangingandtyping.
